Let's see...you have Christopher Nolan, who's one of the best directors of our time. You've got the same writers from the very beginning. You've got a great core cast. And you've got a ton of Batman villains that have never been used before that'll be great assets for a third and maybe final film of Nolan's series(Black Mask, Hush, Deadshot to name a few besides the already-rumored Riddler and Catwoman).

And, again, you have Christopher Nolan who is not worrying about making the third film more epic than The Dark Knight, but to only keep the emotion and suspense that the last two films had, while keeping a strong theme(s) in the film and bringing Batman back out of the shadows and as the hero once more.

Yes, I think this film can escape the third film curse. Of course it can; I have no doubts about that.
